DEVICE ROR TIGHTENING BANJO-HEADS.

SPECIFICATION forming part of Letters Patent No. 288,679, dated. November 20, 1883, Application filed February 19, 1883. (No model.)

To aZZ whom, it may concern:

Be it known that I, HENRY O. TALLMADGE, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Brackets for Tightening the Heads of Musical Instruments, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical section of a banjo, showing attachment of bracket. Fig. 2 is a view of the separate parts of the bracket. Fig. 3 is a sectional View of the tube 1) of the bracket.

Similar letters of reference in the several drawings indicate the same parts.

My invention relates to devices for tightening the parchment heads of musical instruments; and it consists of abracket having the following parts: Referring to the drawings, Fig. 2, b is a tube having an interior screwthread, as shown in Fig. 8, an exterior screwthread cut on its lower edge, and a nut-like enlargement, 11, near its upper end. The in terior and exterior screw-threads run in opposite directions. 0 is a hook adapted to engage with the rim of a musical instrument. In Fig. 1 the hook c is shown attached to the rim R of a banjo. The hook chas on one side a ring, 0, and is perforated by a screw-hole, c. d is a screw-cap adapted to fit onto the lower end of tube 1). e is an upper hook having a screw-thread cut on its shank and adapted to screw into tube 6. f is a screw to be screwed through the rim of the instrument and into hook c at 0'.

My invention is used as follows: Referring to Fig. 1 of the accompanying drawings, the hook c is attached to the lower side of the rim R by passing the screw f through the rim and into the hook c at c.

The tube b is then passed through the ring 0 of hook c, and the screw-cap (Z is screwed onto the tube below the ring 0. The tube b is free toturn in the ring 0, but the cap (Z prevents its withdrawal. The upper hook, e, is then hooked over the upper side of the hoop on the rim R, and is screwed into the tube 1) by turning the said tube either with the fingers or by a wrench applied at the nut-like enlargement of the tube 1).

Fig. 1 shows my bracket in position.

I am aware that screw-brackets for musical instruments have heretofore been made, and I do not claim the screw, broadly.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is as follows 1. A straining device for banjos, consisting of upper hook to engage with the small hoop, having screw-threaded shank, lower hook to engage with the bottom of the large hoop, having eye 0, and the tube I), having nut-enlargement 1), engaging with and adjustable on the screw-threaded shank of the upper hook, and lower screw threaded end provided with a cap, (Z, and turning freely in the eye of the lower hook, as set forth.

2. The combination of upper hook, c, having screw-threaded shank, lower hook, c, having eye 0, screw-hole c, and securing-screw f, and the tube b, formed with nut-enlargement b, for adjusting the upper hook, having screw threaded lower end provided with cap (1, and turning freely in the eye, as set forth.

The foregoing specification of my invention signed by me this 8th day of February, A. D. 1883.

HENRY o. TALLMADGE.
